195 Campers
8:7 = Boys: Girls
8/15 : 7/15
8/15*195 = 104
7/15*195= 91
Therefore, there are 104 boys and 91 girls.
Answer:
Step-by-step explanation:
2x + 20° = 3x - 10° ( being corresponding angles )
3x - 2x = 20° + 10°
x = 30°
The answer is 5.2π in² = 16.3 in²
The area (A) of the circle with radius r is: A = r²π
It is known:
π = 3.14
t = 5
⇒
A = r²π = (16/7)²π = (2.28)²π = 5.2π = 5.2 · 3.14 = 16.3 in²
Answer:
232 ft above sea level
Step-by-step explanation:
He started at -49 ft and then he was later 281 ft higher than that... so just do -49+281 or 281-49= 232
Answer: Only one triangle is possible.
Step-by-step explanation:
Triangle inequality says that if sum of any two sides of the traingle is greater than the third side, then the triangle is possible.
Here,
,
Therefore, a triangle is possible with the given measurements,
Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,
By SSS congruency criteria both the triangles will be congruent.
Thus, all triangles with same measurement will be congruent to each other.
Hence, only one triangle is possible.
